If you have Parallels Desktop for Mac Pro or Business edition you can reset preset network settings for the whole Parallels Desktop application by going to > Preferences > Network > Restore Defaults.

Bridged Ethernet Networking

When operating in the Bridged Ethernet mode, your virtual machine appears on the network as a stand-alone computer with its own IP address and network name.

The Bridged Ethernet networking mode is more complex than the Shared Networking mode, and you may need to contact your system administrator to configure it properly.

To configure your virtual machine to work in the Bridged Ethernet mode:

1. Choose Configure from the Virtual Machine menu to open the Virtual Machine Configuration dialog.
2. Select Network Adapter in the Hardware list.
3. On the Network Adapter pane, make sure that the Enabled, Connected and Bridged Ethernet options are selected.
4. Select the appropriate network adapter from the list. To connect the virtual machine's adapter to the active network adapter of your physical computer, choose Default Adapter.

   In the MAC Address field, you can change the MAC address currently assigned to the virtual machine. MAC addresses are automatically generated during the virtual machine creation. However, you can modify the default MAC address by typing another value in the MAC Address field or clicking the Generate button. When entering a new MAC address, make sure that it is unique within your network.

5. Click OK.

If you cannot configure your virtual machine to function in the Bridged Ethernet mode, you can consider using another networking mode: Shared Networking or Host-Only Networking.

For the information about troubleshooting networking problems, refer to the Parallels knowledge base available at the Parallels website.

Hello all –
I am long time Hackintosh user. I have had this current build for a year to a year and a half. It could not be more stable. It’s my Plex server, work desktop, and I run 3-4 virtual machines on this rig. 2 Linux and 1 Windows Server.
The virtual machine is where I have my issue. I have tested this with Parallels and Virtual Box with the same outcome. I am using Ubuntu 17.x and Mint 19 on both Parallels and VirtualBox. Whenever my host (which is the Hackintosh, we will call it MAC01) loses network connectivity the virtual machines do not recover. MAC01 recovers just fine. I have to restart both virtual machines and restart the entire application as well in order to restore network connectivity to the virtuals. They never disconnect, unless the host loses network connectivity. I can do this by rebooting the switch or pulling out the Cat6 from MAC01. I am running all virtuals with bridged networking.
The thing that leads me to the Hackintosh is, I have an old Mac Mini running with 2 virtuals and when the network drops on that, both virtual machine networks recover without any interaction. I did some reading and my ethernet Kext is the only thing that’s coming to mind as being an issue. Ive seen threads say the Apple one should be installed.
I am using:
Kext name: IntelMausiEthernet.kext
Location: /Library/Extensions/IntelMausiEthernet.kext
Version: 2.2.0
